Oceanic vertical mixing: a review and a model with a nonlocal boundary layer parameterization
TL;DR: In this article, a new parameterization of oceanic boundary layer mixing is developed to accommodate some of this physics, including a scheme for determining the boundary layer depth h, where the turbulent contribution to the vertical shear of a bulk Richardson number is parameterized.

Sub-regional ecosystem variability in the Canary Current upwelling
Javier Arístegui,Eric D. Barton,Xosé Antón Álvarez-Salgado,A. Miguel P. Santos,Francisco G. Figueiras,Souad Kifani,Santiago Hernández-León,Evan Mason,Eric Machu,Hervé Demarcq +9 more
TL;DR: In this paper, a comparative exploration of the biogeographical characteristics of different sub-regions comprising the Canary Current upwelling ecosystem (CanC) is presented, and it is shown that variability in coastline configuration, shelf width, coastal upwell, nutrient fertilization, productivity, or retentive vs. dispersive physical mechanisms may help explain subregional differences in fish distributions and abundances in the CanC.

Physical oceanography of the western Iberia ecosystem: Latest views and challenges
Paulo Relvas,Eric D. Barton,Jesus Dubert,Paulo B. Oliveira,Álvaro Peliz,J. C. B. da Silva,A. Miguel P. Santos +6 more
TL;DR: In this paper, the mesoscale physical processes recognized in the Western Iberia Ecosystem, complementing earlier reviews dedicated to larger scales, have been investigated, and the authors support the idea that these processes, superimposed on larger scale variability, are the major factor controlling the ecosystem functioning in the region.

Influence of environmental and anthropogenic factors on the composition, concentration and spatial distribution of microplastics: A case study of the Bay of Brest (Brittany, France).
Laura Frère,Ika Paul-Pont,Emmanuel Rinnert,Sebastien Petton,J Jaffre,Isabelle Bihannic,Philippe Soudant,Christophe Lambert,Arnaud Huvet +8 more
TL;DR: The presence of buoyant microplastics (PE, PP and PS) in sediment suggests the existence of physical and/or biological processes leading to vertical transfer of lightweight microplastic in the Bay of Brest, and it is suggested that the observed spatial MP distribution is related to proximity to urbanized areas and to hydrodynamics in the bay.

The regional oceanic modeling system (ROMS): a split-explicit, free-surface, topography-following-coordinate oceanic model
TL;DR: In this paper, a split-explicit hydrodynamic kernel for a realistic oceanic model is proposed, which addresses multiple numerical issues associated with mode splitting, and is compatible with a variety of centered and upstream-biased high-order advection algorithms, and helps to mitigate computational cost of expensive physical parameterization of mixing processes and submodels.

Open boundary conditions for long-term integration of regional oceanic models
TL;DR: In this paper, an adaptive algorithm where inward and outward information fluxes are treated separately is proposed, and a volume constraint based on global correction of normal barotropic velocities improves the overall performances of the open boundary conditions.

Propagule dispersal distance and the size and spacing of marine reserves
TL;DR: This study compiled available information on the dispersal distance of the propagules of benthic marine organisms and used this information in the development of criteria for the design of marine reserves, suggesting that reserves be designed large enough to contain the short-distance dispersing propagules and be spaced far enough apart that long-distance dispersed propagules released from one reserve can settle in adjacent reserves.

A method for computing horizontal pressure-gradient force in an oceanic model with a nonaligned vertical coordinate
TL;DR: A pressure-gradient algorithm that achieves more accurate hydrostatic balance between the two components and does not lose as much accuracy with nonuniform vertical grids at relatively coarse resolution, and generalized the monotonicity constraint to guarantee nonnegative physical stratification of the reconstructed density profile in the case of compressible equation of state.
